好的,所以我有了CameraList,扩展了GalleryList,扩展了ListFragment:

public static class FavoritesList extends GalleryList {

    public static FavoritesList newInstance(int page) {
        FavoritesList list = new FavoritesList();

        Bundle args = new Bundle();
        args.putInt("page", page);
        list.setArguments(args);

        return list;
    }

    @Override
    public void onCreate(Bundle saveInstanceState) {
        super.onCreate(saveInstanceState);

        Cursor cursor = dbHelper.getGalleries(fav, preferences.getString("sort"+fav, "date desc"));
        listAdapter = new GalleryListAdapter(activity, cursor);
        setListAdapter(listAdapter);
    }

    ...

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        super.onCreateOptionsMenu(menu, inflater);
        menu.add(Menu.NONE, 0, 8, "Remove All");
    }

    @Override
    public void onPrepareOptionsMenu(Menu menu) {
        super.onPrepareOptionsMenu(menu);

        //listAdapter is null the first …
